LM211 - Voltage comparator
The LM211, LM311 are voltage comparators that have low input currents.
They are also designed to operate over a wide range of supply voltages: from standard ±15 V operational amplifier supplies down to the single +5 V supply used for IC logic.
Their output is compatible with RTL-DTL and TTL as well
